Beschreibung
Zusammenfassung:	This light source device includes: a wavelength conversion element that absorbs a portion of an incident first color beam and outputs a second color beam in a wavelength region that is different from a wavelength region of the first color beam, and outputs an unabsorbed portion of the first color beam; a first optical system that outputs the first color beam toward the wavelength conversion element, while concentrating the first color beam, and sets a focal position of the first color beam to a position shifted from a position on the wavelength conversion element; and a second optical system that is disposed on light output side of the wavelength conversion element, and includes an optical member that concentrates light on a different position depending on a wavelength.
